Faq on alertMetalGuard detection installations

There are several ways to “cheat” any Electronic Article Surveillance system (EAS).
You can cut the pin or you can open it with an illegal detacher or a strong magnet in order to remove it.Since both of these methods take time professional shoplifters nowadays have changed to all kinds of "booster bags.", tinfoil lined bags, and clothes protecting against detection in the EAS-gate!

A booster bag is not always a bag! It can also be any container.The foil shields the security tag from the EAS system, thus allowing stolen items to pass through the system without setting off the alarm.

A foil-lined coat is often used in wintertime and can be a very effective shield against detection in the EAS-system. In fact, some U.S. states are now passing legislation that makes it illegal to wear certain types of clothing while shopping, including aluminum underwear.

YES! Using a booster bag, the thief can steal a lot in just one visit. Within seconds 15 expensive shirts or 4-5 bottles of the finest perfumes easily disappear into the booster-bag! Understanding that one can easily work out the numbers and see that a Metalguard installation can bring ROI very quickly!.

The sensitivity can be adjusted according to the needs of the specific store. The weight of the metal object is not what is measured, rather it is the physical size. In other words, sensitivity can be adjusted so that mobile phones and other small metal objects will not trigger the system.

All products from Alert Systems – as the only patented systems on the market – has a special adjustment that allows installation close up to sliding doors, folding doors, rotating doors and bi-folding doors.

Usually the Metalguard and Hyperguard are installed next to exterior doors.
In larger stores extra installations can be made next to escalators/stairs, or near the entrance to the individual department.
